Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a high-precision motor manufacturing auxiliary robot. Background Technology

[0002] As a core device for energy conversion, electric motors are indispensable basic components in fields such as industrial automation, new energy vehicles, robotics, and consumer electronics. With the rapid development of these industries, unprecedentedly high demands have been placed on the performance, efficiency, reliability, and consistency of electric motors. Modern electric motors, especially precision micro-motors and high-end drive motors, have increasingly complex internal structures and require extremely high assembly precision. Manual operation inevitably involves fatigue and variability, leading to significant fluctuations in product consistency and reliability. Therefore, it is necessary to design high-precision auxiliary robotic arms for motor production.

[0003] To address this, patent CN216707491U discloses a high-precision production auxiliary robot system for micro-motor housings. The system includes a connecting base with two sets of clamping claws symmetrically arranged on both sides of its lower end. A limit push plate, an annular plate, is positioned between the two sets of clamping claws. The lower end of the connecting base has a motor chamber with sliding channels on both sides. The clamping claws include a motor, a sliding block, several clamping rods, and several connecting rods. The motor is fixed within the motor chamber, and the sliding block is horizontally slidably positioned within the sliding channels. The motor's output screw is threadedly connected to a screw hole within the sliding block. Several clamping rods are arranged circumferentially around the sliding block, with one end of each rod hinged to one side of the lower end of the connecting base. Several connecting rods correspond one-to-one with the clamping rods, with both ends hinged to the sliding block and the clamping rods, respectively. When the sliding block moves horizontally, it causes the clamping rods to clamp or open. This invention provides excellent clamping performance for micro-motor housings and is not easily damaged.

[0004] Although the high-precision production auxiliary robot system mentioned above has a good clamping effect, it is inconvenient to adjust the clamping force according to the parts, and the workpiece is easily damaged during use. Therefore, it is necessary to design a high-precision motor production auxiliary robot. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-precision motor production auxiliary robot, including a top base;

[0007] The top seat has a movable structure inside, and mounting brackets are fixed on both sides of the top of the top seat.

[0008] The bottom end of the moving structure is fixed with a steering structure, the bottom end of the steering structure is fixed with a control structure, the control structure includes a protective box fixed to the bottom end of the steering structure, an electric telescopic rod is fixed inside the protective box, a connecting rod is fixed to the bottom end of the electric telescopic rod, and the control structure also includes pressure sensors fixed to the inner walls on both sides of the bottom of the clamping structure.

[0009] The bottom of the protective box is fixed with a clamping structure, and a laser diode is fixed at the middle position of the bottom of the clamping structure.

[0010] Furthermore, the movable structure includes a movable block disposed at the bottom of the top seat, the movable block being internally threaded with a lead screw, and guide shafts being disposed on both sides of the lead screw. The movable structure also includes a first servo motor fixed to the outer wall of one end of the top seat, and an electric push rod fixed to the bottom end of the movable block.

[0011] Furthermore, one end of the lead screw extends to the outside of the moving block and is fixedly connected to the output end of the first servo motor, the other end of the lead screw extends to the inside of the moving block and is rotatably connected to the moving block, and both ends of the guide shaft are fixedly connected to the inner wall of the top seat.

[0012] Furthermore, the steering structure includes a connecting seat fixed to the bottom end of the electric push rod, a connecting plate rotatably connected to the bottom end of the connecting seat, a second servo motor fixedly installed on one side of the connecting seat, a drive gear fixedly installed at the output end of the second servo motor, and a driven gear fixed on the outer wall of the connecting plate.

[0013] Furthermore, the drive gear and the driven gear are meshed together.

[0014] Furthermore, the bottom end of the connecting rod extends to the outside of the protective box and is fixedly connected to the top of the clamping structure, and the pressure sensors are symmetrically distributed on both sides of the clamping structure.

The second servo motor, in conjunction with gear transmission, enables precise stopping at any angle, facilitating adjustments to the gripper's posture to adapt to different gripping and assembly angles of the motor. This enhances the flexibility of the gripper during use, giving the device easy movement and steering capabilities, and improving the convenience of using this high-precision motor production auxiliary robot.

[0022] By incorporating a clamping structure with a V-shaped groove on the inner side of the mechanical claw, the clamping stability of the mechanical claw can be improved, preventing the workpiece from tilting or deforming during clamping. It can adapt to workpieces of different sizes within a certain range. The multi-link hinge structure makes the clamping stable and rigid, realizing the function of easy workpiece clamping and improving the convenience of using this high-precision motor production auxiliary robot.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 The high-precision motor production auxiliary robot provided by this utility model includes a top base 1.

[0031] Reference Figures 1-5 The top seat 1 is internally provided with a movable structure 2. The movable structure 2 includes a movable block 21 located at the bottom of the top seat 1. A lead screw 22 is threadedly connected to the inside of the movable block 21. Guide shafts 23 are provided on both sides of the lead screw 22. The movable structure 2 also includes a first servo motor 24 fixed to the outer wall of one end of the top seat 1. An electric push rod 25 is fixed to the bottom end of the movable block 21. One end of the lead screw 22 extends to the outside of the movable block 21 and is fixedly connected to the output end of the first servo motor 24. The other end of the lead screw 22 extends to the inside of the movable block 21 and is rotatably connected to the movable block 21. Both ends of the guide shaft 23 are fixedly connected to the inner wall of the top seat 1. Mounting brackets 7 are fixed on both sides of the top of the top seat 1.

[0032] When an external power source is connected, the first servo motor 24 is started. The rotation of the first servo motor 24 will drive the lead screw 22, which is fixed to its output end, to rotate. Since the moving block 21 and the lead screw 22 are threadedly connected and its movement is restricted by the guide shafts 23 on both sides, the rotational motion is converted into a precise linear motion of the moving block 21 along the direction of the guide shaft 23. An electric push rod 25 is fixed at the bottom of the moving block 21, thereby driving the entire actuator below it to move horizontally together.

[0033] Reference Figures 1-5 The bottom end of the moving structure 2 is fixed with a steering structure 3. The steering structure 3 includes a connecting seat 31 fixed to the bottom end of the electric push rod 25. The bottom end of the connecting seat 31 is rotatably connected to a connecting plate 35. A second servo motor 32 is fixedly installed on one side of the connecting seat 31. A drive gear 33 is fixedly installed at the output end of the second servo motor 32. A driven gear 34 is fixed on the outer wall of the connecting plate 35. The drive gear 33 and the driven gear 34 are meshed together.

[0034] When an external power source is connected, the second servo motor 32 is started, driving the drive gear 33 at its output end to rotate. The drive gear 33 meshes with the driven gear 34 fixed on the outer wall of the connecting plate 35. Since the connecting plate 35 is rotatably connected to the connecting seat 31 above, the meshing transmission between the driven gear 34 and the connecting plate 35 converts the rotational motion of the second servo motor 32 into the rotational motion of the connecting plate 35 around its axis. The rotation of the connecting plate 35 drives the entire control structure 4 and the clamping structure 5 below it to rotate in the horizontal plane, which makes it easy to adjust the clamping direction of the clamping structure 5.

[0035] Reference Figures 1-5A control structure 4 is fixed to the bottom of the steering structure 3. The control structure 4 includes a protective box 41 fixed to the bottom of the steering structure 3. An electric telescopic rod 42 is fixed inside the protective box 41. A connecting rod 43 is fixed to the bottom of the electric telescopic rod 42. The control structure 4 also includes pressure sensors 44 fixed to the inner walls on both sides of the bottom of the clamping structure 5. The bottom of the connecting rod 43 extends to the outside of the protective box 41 and is fixedly connected to the top of the clamping structure 5. The pressure sensors 44 are symmetrically distributed on both sides of the clamping structure 5. A clamping structure 5 is fixed to the bottom of the protective box 41. The clamping structure 5 includes a mechanical claw 51, a limiting rod 52, a drive rod 53, a connecting wall 54, a connecting block 55, and a mounting plate 56. The mounting plate 56 is fixed to both sides of the bottom of the protective box 41. Connecting blocks 55 are provided on the inner side of the top of the clamping structure 5. Connecting walls 54 are hinged to the outer walls at both ends of the connecting blocks 55. A drive rod 53 is hinged to the bottom of the connecting wall 54. A mechanical claw 51 is hinged to the bottom of the drive rod 53. A limiting rod 52 is hinged to the top of the mechanical claw 51 on the side away from the drive rod 53. The mechanical claws 51 are symmetrically distributed on both sides of the connecting blocks 55. The top of the limiting rod 52 is hinged to the inner wall of the mounting plate 56. The turning point of the drive rod 53 is hinged to the inner wall of the mounting plate 56. A laser diode 6 is fixed at the middle position of the bottom of the clamping structure 5. A microcontroller is installed inside the laser diode 6. A photodetector is provided on the outside of the laser diode 6. The input end of the laser diode 6 and the output end of the back-end terminal are electrically connected through the microcontroller.

[0036] An external power source is used, with the electric telescopic rod 42 serving as the power source. It is fixed inside the protective box 41, and the end of its push rod is fixed to the connecting rod 43. When the electric telescopic rod 42 is energized and extends or retracts, it pushes the connecting rod 43 to move vertically in a straight line. The bottom end of the connecting rod 43 extends out of the protective box 41 and is fixed to the top of the connecting block 55, thus directly driving the connecting block 55 to move up and down. When the connecting rod 43 moves downward, it pushes the connecting block 55 downward. The downward movement of the connecting block 55 is converted into the horizontal outward movement of the mechanical claw 51 through two sets of hinged drive rods 53 and the connecting wall 54, thereby achieving the opening mechanism. When the connecting rod 43 moves upward, it pushes the connecting block 55 upward. The upward movement of the connecting block 55 is converted into the horizontal inward movement of the mechanical claw 51 through the two sets of hinged drive rods 53 and connecting wall 54, thereby realizing the clamping action. The pressure sensor 44 is symmetrically installed on the inner wall of the mechanical claw 51 to monitor the force applied by the mechanical claw 51 when clamping the workpiece in real time. The pressure sensor 44 is equipped with a microcontroller. The pressure sensor 44 can feed back pressure data to the electric telescopic rod 42 through the microcontroller to control the lifting and lowering amplitude of the electric telescopic rod 42, thereby controlling the clamping force of the clamping structure 5.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
